NS_E_AUDIODEVICE_UNEXPECTED: the failing boundary
NS_E_AUDIODEVICE_UNEXPECTED (0xC00D1B62) means It is not possible to open the specified audio capture device because an unexpected error has occurred. The important boundary is audio capture initialization; do not replace this result with a broader “Windows Media failed” diagnosis.
What this result proves
This code proves that the selected audio device returned an unclassified error while being opened. It does not, by itself, prove a codec, permissions, network, device, or media problem outside that boundary. Preserve the first lower-level result when one exists, because later Player or Encoder errors can hide the original cause.
Evidence and focused verification
Record endpoint, driver, requested format and first lower-level capture result; test one native format in a fresh capture instance. Keep the media object, endpoint, profile, or device identity fixed while changing only that rejected precondition. A successful retest should pass this exact boundary; a different HRESULT from a later stage is new evidence, not recurrence of NS_E_AUDIODEVICE_UNEXPECTED.
